Nginx-rtmp-module: ffmpeg exec command not running in nginx rtmp

[evangeline123]

I am using nginx and rtmp module to stream live hls and mpeg-dash.
here is my rtmp command in nginx .conf

rtmp {
server {
    listen 1936;


    application mypull {
    live on ;
    meta copy;
    allow play all;

    pull rtmp://184.72.239.149/vod/BigBuckBunny_115k.mov name=test live=1;


    exec_push   /usr/bin/ffmpeg -re -i rtmp://localhost:1936/mypull/$name -vcodec libx264 -acodec libmp3lame -f flv rtmp://localhost:1936/hls/$name;


}


application dash {
        live on;
        dash on;
        dash_path /tmp/dash;
        dash_nested on;
        dash_fragment 5s;
        dash_playlist_length 30s;
    }
     application hls {
        live on;
        hls on;
    hls_playlist_length 30s;
    hls_fragment 5s;
        hls_path /tmp/hls;
    }
}
}

but it is not playing. it seems that the ffmpeg command is not even running. and the hls and dash folders are empty. could anyone help me with it?

[jadsonlourenco]

I have the same question, thanks!

[zorrigas]

Use a SH file.

Config:
exec /opt/hls.sh $name;

Example SH File:
ffmpeg -i rtmp://localhost/live/$1 -async 1 -vsync -1 -c:v libx264 -c:a ...

Works for me!

[aamelegy]

it could be nginx trying to run the command but fails for some reason, may be a missing codec for example. try running your command without nginx and see if it is working without errors

[begetan]

I am using directive exec_static in this case.

Just replace exec_push with above one. It will start streamig immediatelly aftere start nginx process.

[sassyn]

Did u manage to solve it?

Nothing works for me in terms of exec command;

server {
listen 1935;
ping 3m;
ping_timeout 30s;
notify_method get;

  application myapp {
     live on;
     exec_options on;

 exec_push /usr/bin/ffmpeg -i rtmp://localhost/src/$name -vcodec libx264 .... rtmp://localhost/hls/$name 2>>/var/log/ffmpeg-$name.log;
   exec_push /usr/bin/ffmpeg -version  > /tmp/xxxx;
   exec_pull /usr/bin/ffmpeg -version  > /tmp/xxxxsss;
   exec_static  /usr/bin/ffmpeg -version  > /tmp/xxxxsss;
   exec /usr/bin/ffmpeg -version  $name  >> /tmp/xxxxsss;
}

}

Nothing seems to work.
I even run the nginx as root user.

I'm also compile with --debug

here is the nginx -v output:

Any idea?
I'm running Ubuntu 16.04. Disable the apparmor. Nothing in the logs, or in dmesg/syslog.

[zorrigas]

Again, use a sh file, and parse name as argument.

exec /opt/hls.sh $name;

[sassyn]

It seems that the issue is with the NGINX version.

See here:
https://github.com/arut/nginx-rtmp-module/issues/886

[begetan]

Here is working config for custom build version 1.11.10 and 1.10.1 on ubuntu:

rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 5000;
        allow play all;

        application src {
            live on;
            sync 50ms;
            exec_static /usr/bin/ffmpeg -i http://192.168.7.4:5112 -c:v libx264 -acodec aac -ac 1 -strict -2 -b:v 1024k -preset veryfast -deinterlace -f flv rtmp://1.2.3.4:1935/live/1tvrus 2>>/var/log/nginx/ffmpeg-1tvrus.log;

            deny publish all;
            deny play all;
        }

Still not working.

I download version 1.11.9
recompile in ubuntu 16.04, rtmp working good! but exec command not running! :-(

What I'm doing wrong?

Hi all,

same with openresty 1.11.2.4 and rtmp module. compiled everything is fine, but not working when use exec_pull or exec_push .

nginx version :

They only works when you publish or play a stream on an application, for example:
application myapp {
live on;
exec_push /usr/bin/ffmpeg -re -i rtmp://localhost/$app/$name -vcodec libx264 -acodec aac -strict -2 -f flv rtmp://localhost/hls/$name;
}

application hls {
live on;
}
When you publish a stream on myapp, then you can subscribe it on both myapp and hls. However, the stream on hls may be different from the stream on myapp, because it was transcoded.

[vmintam]

Hi winshining,
this is my nginx rtmp config :

rtmp {
        server {
                listen 1935;
                chunk_size 4096;
        application myapp {
                  live on;
                  exec_push /usr/bin/ffmpeg -i /tmp/test.sdp -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv rtmp://127.0.0.1:1935/live/testing;
                  }

                  application live {
                  live on;
                  }
        }       
}

when i use VLC join to rtmp://127.0.0.1/live/testing ---> nothing happen.
but when i use command :
ffmpeg -i /tmp/test.sdp -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv "rtmp://127.0.0.1/live/testing"

everything is fine.

any suggestion for me ?

thanks!

Nice Job!

I solved this problem by adding below in first line of nginx.conf.

[winshining]

@vmintam Try to push a stream to myapp, and then use vlc to join rtmp://127.0.0.1/live/testing.
In fact, it's not suggested to use it as you set, the purpose of exec_push is to relay your push from one app to anohter:

rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application myapp {
            live on;
            exec_push /usr/bin/ffmpeg -re -i rtmp://127.0.0.1:1935/$app/$name -ar 44100 -vcodec libx264 -acodec libmp3lame -f flv rtmp://127.0.0.1:1935/live/testing;
        }

        application live {
            live on;
        }
    }
}

Then, you can push to myapp, play on live:)

[neuronetv]

I have the same problem - ffmpeg doesn't run when I start nginx. My question is: how would one find out what the error is? On my centos 6 server there's nothing in the console when I start nginx, I can't find an nginx log anywhere. I have a similar nginx.conf file as previous posts here and if ffmpeg won't start there must be a reason recorded somewhere. Thanks for any pointers.

[zunair-syed]

same here. trying to run the following:
exec_static /usr/bin/ffmpeg -re -i rtmp://localhost:1935/hls/$name -c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128K -f flv rtmp://localhost:1935/hls/$name_low -c:a libfdk_aac -b:a 64k -c:v libx264 -b:v 256k -f flv rtmp://localhost:1935/hls/$name_mid -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/hls/$name_hi -c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost:1935/dash/$name_dash > /home/zsyed/Documents/logs.txt;

This is the issue, which I faced. Infact, redirecting the output of ffmpeg somewhere in /tmp can tell you the exact reasons. In my case, it was permission issue and it works fine. I am using as follow:

exec_push ffmpeg -i rtmp://localhost:1935/myapp/$name -c:v copy -c:a copy -segment_time 120 -f segment -reset_timestamps 1 -strftime 1 /opt/test_utils/$name_rtmp.mp4 2>>/tmp/ffmpeg.error;

I have the same question, thanks!
The version I use is ngixn-1.18.0
I run the exec command in rtmp and it still doesn't work。

As mentioned above, I had changed the configuration and had permission issue( running under docker container). For me it had worked long back and using into production since then.

[jeffbski-rga]

I found that I just needed to include the full path to ffmpeg and that fixed my problem. You can find the path using which ffmpeg

Using the latest nginx/1.19.6 and latest nginx-rtmp

I used this in my nginx.conf

exec /usr/local/bin/ffmpeg ...
